I'm looking for a fic, I think it was a response to one of the prompt memes, in which Kurt speaks (not swears in, that's a different fic) a number of a different languages (it might be a 5 and 1 fic, but I'm not sure). Some scenes I remember are Kurt arguing in German with his dad, Rachel walking in on him watching a Japanese movie without subtitles or dubs, and I think he speaks Dutch with Brittany at one point, who may have taught it to him. Near the end the Glee club members are comparing and realize he speaks far more languages than they thought.
Sound familiar to anyone?
